Huawei, Ericsson, Nokia and ZTE are the top small cell suppliers in the world, according to the latest report from Dell’Oro Group.

Small cell radio access network (RAN) revenues increased 15 percent in the first quarter, growing at a faster pace than the broader small cell plus macro RAN market. Global small cell RAN revenues remain on track to surpass $5 B in 2022.

“The fact that small cell investments are advancing at a rapid pace even as the operators are intensifying their 5G macro roll out efforts show that small cells are an essential part of the broader RAN toolkit,” said Stefan Pongratz, Vice President at Dell’Oro Group.

Nearly all the small cell growth is driven by public 5G – small cell LTE revenues declined in the quarter and private 5G small cell investments are still negligible.
